Yes they are horrid at messaging and that is not likely change so what is the point of focusing on it? Barring impeachment here is there for four more years and shows no signs of getting any better at not saying dumb shit. They pride themselves on not being PC and not prepacking and testing everything before they say, or hell even making sure it is true.
At this point it seems more likely we will spend the next four years more focused on what they say than what they do. If that happens than he may be right and he may have a much better brain than we give him credit for.
If someone is inept in the real world they either get better or they get fired. Simple fact checking is not hard to do. This is not about political correctness. This is about communicating effectively and eloquently. Something the Press Secretary must do. He risks becoming news rather than delivering the message. And that is not good for him or for the President.
I think you're just being recalcitrant here on purpose for whatever reasons you think important. But you and I clearly don't see eye to eye on this so I leave you with this - До свидания.
